A 254 mm (10 in) Aluminum Caliper for transferring a measurement from one piece to the next. Light enough to leave on the wheel head.

AL10 is the 254 mm (10 in) caliper in Kemper's aluminium range. The use is not really measuring, it is repeating: set the arms to the inside diameter of a gallery and every lid you throw afterwards can be checked against the same setting without a ruler entering the conversation. Aluminium keeps it light, which matters because a caliper lives on the wheel head next to wet hands rather than in a drawer. Kemper makes 8, 10 and 305 mm (12 in) versions; pick by the largest diameter you actually throw.
